I'm in Utah, and it's currently the general elk hunt. While driving/crawling on rocky roads/trails, the jeep would randomly die. I'd pop the trans in neutral and it'd start right back up. This started Saturday. Starting back in June every once in a while I would smell raw gas from the engine compartment. No obvious signs of a leak. Also, about the last 4-5 weeks when the engine is warm, I have to turn the key on, let the fp pressure up, turn it off, then back on, let it pressure up and crank it to start it. When the pump/engine is running, I get 58psi. But it doesn't hold any pressure when the pump is off. It quickly drops to zero as soon as I turn off the key. This week, in addition to the jeep dying when driving slow, it's also doing it in park, or intermittently when slowing down to stop. Do I have a bad check valve/pressure regulator? Bad or stuck open injector?
Since this is an intermittent issue, I kept trying to get it to have problems while I had the fuel pressure gauge connected. I videoed my fuel pressure gauge, and this time, it was bouncing around, but still within 58 psi +/- 5. And then, just before it dies, there's a swoosh sound. Air blowing out or in. I don't know where exactly since it doesn't always do it. On the video it sounds like a squeak, but it's definitely a burst of air sound.
